<p>An electromagnetic contactor comprises a main circuit section (8) having a vacuum valve (1) incorporating a fixed contact (1a) and a movable contact (1b), an insulating frame (2) for containing and holding the vacuum valve (1), an insulating rod (6) linked to the movable contact (1b) side, and a pressure spring (7), a drive mechanism section (17) having an open/close lever (10) for reciprocating the insulating rod (6) in the approaching/receding direction of both contacts, a rotary shaft (11) provided on the side of fulcrum of the open/close lever (10), a moving element (12) bonded to the rotary shaft (11), and an electromagnet (13) for rotating the rotary shaft (11) by attracting the moving element (12), and a base (9). In the electromagnetic contactor, the main circuit section (8) is fixed to the base (9) through the insulating frame (2) and the drive mechanism section (17) is fixed to the base (9) not through the insulating frame (2).</p> |
